tank breather dropping fuel

[mgglep]

Hi all
I have used a pipe off the sender to vent the tank which loops up as high as I can get it then back down to vent the tank
I took my car on a track day yesterday and on severe corning I was dropping fuel on the track from the breather
My filler doesn't have a breather connection
Just wondered if anyone else has encountered this and if they have a solution
Many thanks

One way valve in pipe near to tank and put rest of pipe up inside roll bar,if end of pipe is at tank level or lower it will syphon,the breather pipe should not be in the fuel.

You can get foam to put in the tank but the sender will not work.
